Jengo refused to poop in his own back yard. Would rather hold it than go there. Instead he’d stare us down for however long it took to get a walk. Most times it wasn’t long because we were already getting ready to go, “Hold on. Gimme a minute.” Never had a dog that refused to poop on his own turf before.
He was also picky about where he’d go even during walks, but he’d eventually always find a spot. There were days when for one reason or another it wasn’t possible to get an afternoon walk in. Pre stroke he never had accidents in the house either. The next morning he’d usually go at least twice though. He was just stubborn that way, but it didn’t seem to be a frequent problem.
What is “Matching.” I’ve not heard of that term.
